Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling large and heavy planks are time-consuming and labor-intensive, leading to slow construction and potential inaccuracies in plank positioning, resulting in increased costs and reduced work efficiency.
Innovation Solution
A positioning and fastening system comprising planks with counterbored holes and nuts, along with a positioning pin and junction bolt, allows for precise alignment and secure fastening of planks, enabling efficient assembly and alignment of planks with either aligned or staggered edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple planks are assembled manually with precise close integrations, then the relative positioning accuracy is improved, but the construction time increases significantly
Solution Approach 1:
The patent pre-provides positioning counterbored holes and pre-burying counterbored holes in the planks before assembly. These pre-positioned holes enable rapid insertion of positioning pins and junction bolts, eliminating the need for manual measurement and positioning during construction, thus resolving the contradiction between positioning accuracy and construction speed
Solution Approach 2:
The patent introduces positioning pins as intermediary components that fit into the pre-positioned positioning counterbored holes. These pins serve as mediators to quickly establish accurate relative positions between planks without requiring manual alignment, thereby improving both positioning accuracy and assembly efficiency
2Ease of operation
If manual assembly techniques are used for large-scale plank structures, then flexibility in operation is maintained, but the quality consistency deteriorates due to size errors
Solution Approach 1:
The patent segments the plank structure into modular units with standardized junction surfaces, positioning counterbored holes, and pre-burying counterbored holes. This segmentation allows each plank to be independently manufactured with precise features, ensuring quality consistency across large-scale assemblies while maintaining operational flexibility through modular construction
Solution Approach 2:
The patent changes the operational parameters by providing pre-positioned holes with specific dimensions and locations in each plank. This parameter standardization ensures that regardless of the scale of the project, the same precise parameters are maintained, guaranteeing quality consistency while allowing flexible assembly operations
3Ease of operation
If lightweight materials are used for planks, then transportation and handling become easier, but the structural strength and durability are compromised
Solution Approach 1:
The patent employs junction bolts with threaded portions that screw into nuts embedded in the planks, creating a curved threading path through the material. This threaded connection provides strong mechanical interlocking that compensates for the use of lightweight materials, maintaining structural strength while allowing easier transportation and handling of the planks

AI summary
A positioning and fastening system for combining planks comprises at least two planks, each of which has a junction surface at one end plane and a clamping surface at the other end plane wherein the junction surface on each of the planks is designed to have a positioning counterbored hole, the clamping surface is designed to have a pre-burying counterbored hole opposite to the positioning counterbored hole, and both the positioning counterbored hole and the pre-burying counterbored hole allow a bolt hole to penetrate in between. For combining the two planks based on the opposite junction surfaces, the two positioning counterbored holes allow a positioning pin to be plugged in and between for positioning, the positioning pin develops a bolt passage centrally, the nut hole inside each positioning counterbored hole of the two planks pre-buried a nut in which a screw hole is prepared centrally, and a junction bolt penetrates from one nut at anyone of the two planks through the bolt passage and is fixed in the screw hole of the nut at the other plank. Based on above components, combining two planks is completed fastly and accurately.
